Application tiled latch 4, 1922. Serial No. 540,959.

To all whom it may concern: Be it known that I, WILLIAM C. HABER- KAMP, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Hair Wavers, of which the following is a specication.

This invention relates to hair dressing devices and especially to that class known as hair curlers, wavers and the like. Heretofore it has been customary to use curling irons and wavers formed of bar members or the like arranged crosswise to operate after the manner of tongs, shears, and such ivotally connected devices, and the e ective members in such devices have been made substantially straight and usually include a pair of relative curved faces arranged to coact concentrically when brought together so as to embrace the hair and apply heat thereto while held .between'the jaws. i

The main objects of this invention are to provide a hair treating implement having an eective heat supplying part formed or curved to correspond substantially with the curvature of the head; to provide such a device adapted to prevent burning the headl of the person whose hair is being treated; to rovide a device ofthe character descri d havin a pair of parallelly disposed effective mem ers connected and provided' with operative means to open and close the Il device with said members always in parallel relation;` toprovidesuch members of substantially flat shape; to provide means for heating one or preferably both of the effective members; to provide adjustable manually controlled electric means to produce the necessary heat; to provide a waver of the character described adapted'to receive successivelyv a series of hair rolls formed by winding wisps of hair upon or around hairpins or ordinary hair curlers; andto provide such a device adapted for use either` by a hairdresser or for treating ones own hair to produce a perfect 'hair wave.

An ilustrativo embodiment of this in- .50. vention is shown in the accompanying drawin in whichlgure 1 shows the waver as applied to the hair.

Fig. 2 is a sidewise view of the device.

Fig. 9 is a plan of the heat control switch as viewed on the line 9--9 of Fig. 4.

Fig. 10 is a view of the plug switch on the line 10-10 of Fig. 2.

In the construction shown in the drawings, the hair waver 1 comprises mainly a pair of handles 2 and 3 operatively connected to a pair of heat supplying pressure jaws 4 adapted and arranged to receive a lock of hair 5 wound upon any suitable su port or curler, as for instance a hairpin` 6. he said handles are preferably similar in general shape and design, and are pivotally joined at 7 adjacent to but s aced somewhat from one end, as shown in re 2. Each handle is connected to the adjacent ends of both jaws 4 on the opposite sides of pivot 7 -respectively, one connection being by means of a non-sliding pivot 8 and the other being by means of a slidably mounted pivot 9. In this instance the pivot 8 is at the inner tip of the handle and the pivot 9 is secured to said handle on the opposite side of pivot 7 and is arranged to slide in the longitudinal slot 10 of the corresponding jaw 4. For this purpose each of said jaws is provided with a rearwardlyextending projection or arm 11 and each'ann contains one of the said slots 10.

As thus constructed the angular operation of the handles moves the jaws toward and away from each other alwa s in a parallel position. In order that the evice may have a positive tendency tofremain open a spring 12 is mounted in one of the handles and is arranged to urge the handles apart, as also the jaws. sion spring 12 is used, one endl being secured to the handle 3 near it outervend as at 12', `and the opposite end being connectedtothe .rearward end of the adjacent arm 11 as at Electric current -i's supplied to the device through a two conductor cord 13 connected to a plug switch 14 as will be understood and as indicated by Figures 2 and 6. From For this purpose a helical tenthe stationary part 14 of this switch .the circuit leads to an automatic control switch l which is actuated by the opening and closing of the device in such manner as to open the circuit when the device is not in use. In order to enable the user to regulate the heat, a manual switch 16 is provided, which is so connected as to enable the operator to move it to one position for parallel connection of the two heater elements 1i", and to another position for series connection as will be more fully explained. Said switch 16 is mounted on a. rearwardly projecting plate 1S secured to the inner pro jection 19 at the rear end of arm 11, adjacent to the handle member 2 whereon the plug switch is mounted. The said reversing switch 16 is provided with laterally projecting rods or push buttons 2O adapted and arranged for ready actuation by the hand of the user, one button being disposed on each side for alternate use as may be required from time to time.

The automatic switch 15 comprises a pair of contact members 21 and 22, the former being mounted on the handle 2. and the latter being secured to the rear end of the outer branch 23 of arm 11 adjacent to said handle. In closing the device said handle 2 and arm 11 swing toward alinement with each other and in so doing carry the contacts 21 and 22 into electrical connection with each other. lVhen the device is released the reverse action occurs and the switch 15 is opened.

Each jaw 4 comprises a housing frame or casing 30, a removable cover 31 secured in place by a screw 32, a heater element or wire 33 wound on a support' 34, insulating material 35 disposed on both sides of the heater element and a heat insulating rim or band 36 disposed around the edge of the jaw to protect the head ofthe user from possible burns.

Although it is preferable to wire the device in accordance with the diagram of F igure 6, it may be used without the manual switch 16, and for simplifying the wiring on Figure 4 it is so shown on said ure, that is to say, the wiring goes past switc 16 without including it. In this instance the wiring 38 is shown leading to the heater element through a passageway 39 in arm 11. Said arm may contain two assageways 39, one for each wire or a sing e larger passageway for both wires.

The operation of the device is as fcllows: When not in use the flexible cord 13 is removed by 'withdrawing the plug 14 from switch 14, but when the device is to be used the plug is then attached. The

` switch 16 is then placed in the position `shown in Figure 6 whereby the elements 17 are placed in parallel so that when the device is closed by gripping the handles and the circuit completed through the switch 15, a maximum heat will be generated. If in use the device gets too hotI the switch 16 is reversed by pressing on the corresponding button 19. It' desired the device may be held closed while warming up to working temperature by a' link 40 slipped on over the ]aws.

Although but one specific embodiment of this invention has been herein shown and described it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
